The first recordings from free-ranging Gervais' beaked whale (Mesoplodon europaeus) are presented. Nine Gervais' beaked whales were observed visually for over 6 h. Clicks were only detected over a 15 min period during the encounter, which coincided with an 88 min period during which no whales were observed at the surface. Click lengths were typically around 200 microS and their dominant energy was in the frequency range 30-50 kHz. While these clicks were broadly similar to those of Cuvier's and…

Click characteristics of northern bottlenose whales (Hyperoodon ampullatus) and Sowerby's beaked whales (Mesoplodon bidens) off eastern Canada.
TLDR
Data from multiple encounters in the western North Atlantic are used to provide a quantitative description of clicks produced by beaked whales, improving the effectiveness of PAM and enhancing scientific understanding and conservation efforts for cryptic and at-risk cetaceans.
Distribution, Abundance and Population Structuring of Beaked Whales in the Great Bahama Canyon, Northern Bahamas
TLDR
The long-term goal of this project is to fill key data gaps on the distribution, abundance, habitat use and population structuring of beaked whales in the Great Bahama Canyon.
A description of echolocation clicks recorded in the presence of True's beaked whale (Mesoplodon mirus).
TLDR
The spectra and measurements of the recorded clicks closely resemble Gervais's beaked whale clicks (Mesoplodon europaeus) and distinguishing between the two species in acoustic data sets proves difficult.
Description of sounds associated with Sowerby's beaked whales (Mesoplodon bidens) in the western North Atlantic Ocean.
TLDR
The acoustic characteristics of Sowerby's beaked whales have not previously been described; the current study will facilitate incorporation of these data into passive acoustic monitoring programs in the North Atlantic Ocean.
Echolocation signals of a beaked whale at Palmyra Atoll.
TLDR
These signals had higher frequencies, broader bandwidths, longer pulse durations and shorter inter-pulse intervals than previously described pulses of Blainville's, Cuvier's and Gervais' beaked whales.
Future Directions in Research on Beaked Whales
Until the 1990s, beaked whales were one of the least understood groups of large mammals. Information on northern bottlenose whales (Hyperoodon ampullatus) and Baird’s beaked whales (Berardius…
Deraniyagala's beaked whale, Mesoplodon hotaula: A review of current status, biology, threats and future research needs
TLDR
Deraniyagala’s beaked whale, Mesoplodon hotaula, was described in 1963, but was quickly synonymized with M. ginkgodens making it one of the least known cetaceans, but sightings and acoustic recordings around Palmyra Atoll are believed to be of this species.
Aleutian Islands beaked whale echolocation signals
Beaked whales are an elusive group of marine mammals. They are infrequently encountered as they are pelagic, deep diving foragers with short surface intervals between long dives (Tyack et al. 2006).…
An acoustic survey for beaked whales in the Rockall Trough
Despite being one of the least known families of cetaceans, it is apparent the beaked whales are sensitive to anthropogenic noise. Understanding the distribution and ecology of these species is…
Passive acoustic monitoring of beaked whale densities in the Gulf of Mexico
TLDR
Methods are presented for the density estimation of beaked whales, using passive acoustic monitoring data collected at sites in the Gulf of Mexico from the period during and following the Deepwater Horizon oil spill.

First record of a stranded Gervais' beaked whale, Mesoplodon europaeus (Gervais, 1855), in the Mediterranean waters
TLDR
This paper reports the first Mediterranean stranding of a Gervais' beaked whale (Mesoplodon europaeus) that took place in 2001 along the northern Tyrrhenian coasts of Italy and is the first report of a MesoplodonEuropaeus in the Mediterranean waters.
Foraging Blainville's beaked whales (Mesoplodon densirostris) produce distinct click types matched to different phases of echolocation
TLDR
Blainville's beaked whales (Mesoplodon densirostris Blainville) echolocate for prey during deep foraging dives using acoustic tags to demonstrate that these whales produce two distinct types of click sounds during different phases in biosonar-based foraging.
CLICK CHARACTERISTICS OF NORTHERN BOTTLENOSE WHALES (HYPEROODON AMPULLATUS)
TLDR
Sounds produced by northern bottlenose whales recorded in the Gully, a submarine canyon off Nova Scotia, consisted predominately of clicks, which suggests that 24 kHz would be optimal for an object of approximately 6 cm or more, consistent with the size range of their squid prey.
Beaked whales echolocate on prey
Beaked whales (Cetacea: Ziphiidea) of the genera Ziphius and Mesoplodon are so difficult to study that they are mostly known from strandings. How these elusive toothed whales use and react to sound…
Echolocation clicks of free-ranging Cuvier's beaked whales (Ziphius cavirostris).
TLDR
Qu quantitative characteristics of clicks from deep-diving Cuvier's beaked whales (Ziphius cavirostris) are reported using a unique data set and the potential for passive detection is enhanced.
Known and inferred distributions of beaked whale species (Cetacea: Ziphiidae)
TLDR
This work has reviewed the known distribution of each beaked whale species and where possible, used this in formation to infer its global distribution and serves to highlight gaps in knowledge.
Biosonar performance of foraging beaked whales (Mesoplodon densirostris)
TLDR
It is suggested that stable ICIs in the search and approach phases facilitate auditory scene analysis in a complex multi-target environment, and that a concomitant low click rate allows the whales to maintain high sound pressure outputs for prey detection and discrimination with a pneumatically driven, bi-modal sound generator.
Mesoplodon europaeus
TLDR
M. europaeus closely resembles M. mirus, but has smaller pectoral flippers than M.Mirus and has a more dolphin-like beak and rounded melon, while the head shape of Cuvier’s beaked whale, Ziphius cavirostris, is blunter and paler in color.
Extreme diving of beaked whales
TLDR
Using current models of breath-hold diving, it is inferred that beaked whales' natural diving behaviour is inconsistent with known problems of acute nitrogen supersaturation and embolism, and possible decompression problems are more likely to result from an abnormal behavioural response to sonar.
Passive acoustic detection of deep-diving beaked whales.
Beaked whales can remain submerged for an hour or more and are difficult to sight when they come to the surface to breathe. Passive acoustic detection (PAD) not only complements traditional…
